Over the next year or so, the tale only got better. Hwang, aided by a tireless, dedicated and underpaid laboratory staff that venerated him, went on to create multiple lines of thriving stem cells with unprecedented efficiency and ease. He topped his performance off last summer with yet another feat that had eluded some of the world's most talented scientists: the first cloning of a dog, called Snuppy. TIME named Snuppy "Invention of the Year" for 2005, but that was merely the icing on a cake of praise and recognition for Hwang. Scientists from around the world were clamoring...
...world of high-level research. Then came the allegation that some of the photos of cells he published did not show what he claimed. And finally, as he was forced to admit two weeks ago, before submitting his resignation to Seoul National University (S.N.U.), that nine of the 11 stem-cell lines he described in Science weren't from clones at all. Last week, in a kind of scientific coup de grace, a university panel declared it could find no evidence to support the validity of the remaining two lines either...
First it was the charge that women in Woo Suk Hwang?s lab had donated their eggs for research, a clear violation of ethical standards. Then came his admission that photographs in a Science paper he published last year on stem cells cloned from human volunteers were phony, which led to a retraction. But when a panel at Seoul National University ruled last week that not just the pictures but much of the data in the Science paper had been faked as well, Woo Suk Hwang, South Korea?s cloning superstar, had to resign...
...that is, the idea of using a patient?s own cells to grow replacement parts for failing tissue. And for Hwang himself, who seemed to be leaving other scientists in the dust, things have gone from bad to worse. He?s still insisting that two of the 17 human stem-cell lines he says he created through cloning are legitimate, but the university is looking into those as well-and sifting through his data on Snuppy, which Hwang presented last summer as the world?s first cloned...
...idea of therapeutic cloning itself. Ambition and pride are a danger in any high-risk, high-reward area of science, but therapeutic cloning is so promising that it needs to be pursued regardless. The potential medical advantages are enormous: by cloning a patient?s own cells to create stem cells, then coaxing those stem cells to become new pancreatic, brain, spinal cord or heart tissue, for example, it?s conceivable that a victim of Parkinson?s, Alzheimer?s, diabetes, paralysis or heart disease could shore up damaged organs with new, healthy and-most important-rejection-proof replacements. (These are embryonic...
